theora - Jul 2004 - A script to convert existing video files to Ogg

(Theora/Vorbis) available.
Message-ID: <410011E4.2040904@hut.fi>

Hello,

I noticed that it's quite difficult currently to create Ogg format files
(Ogg Theora for video and Ogg Vorbis for audio). There's only the
encoder_example-program, which is included in the libtheora source
packages, but seemingly not in any libtheora/libtheora-devel packages
that are around the web for e.g. many Linux distributions.

If anyone happens to be interested in an easier way to utilize Ogg
Theora, I've made the encoder_example binary available as an RPM package
(compiled under SUSE 9.1), together with an easy-to-use script with
which to convert videos to Ogg format. The RPM requires libogg,
libtheora and libvorbis installed, and the script (2ogg.sh) needs
MPlayer (http://www.mplayerhq.hu/) and encoder_example. I put the
2ogg.sh under GPL just in case someone wants to do something with it.

They're available at my home page at:
http://www.iki.fi/~tjyrinki/proj_info.html#convtheora

I haven't programmed much with the shell scripts, but I tried to do some
proper parsing of the paramaters so that it's both easy and safe to use.
There's nothing earth-shattering in the script, but I find it a nice
thing to have together with a ready-to-go encoder binary.

Best Regards,
Timo Jyrinki

regarding 2ogg.sh some suggestions.
mkfifo -m 660 stream.yuv does not work on FAT filesystem. Please make a
check that, filesystem on which, you run the script is not FAT/NTFS.
Default video and audio quality should be there (if user does not
provide any arguments). For me, video=3 and audio=2 works great.

I am using SuSE 9.1, with many rpms installed using apt4rpm. RPMs in
repository, include encoder_example.

Thanks for the suggestions. I made the changes (amongst a few others) and made
version 0.01a available. It seems, though, that not every version of df (which I
used) has the --exclude-type option available, so if you have a more trustworthy
way of detecting FAT/NTFS, feel free to tell. At least on one Solaris machine
the detection doesn't work and running the script fails (then again, I
don't
know if mplayer works on Solaris either?).

I didn't actually even test the detection itself, as I don't have any
FAT or
NTFS partitions. I just tried it with vfat (or ntfs) replaced with reiserfs and
it worked, so I assume it's okay.

BR,
